To-ell whom it may concern: I Be it known that I, JOHN J. HEYs,-a citizen of the @United States, residing at Lynn, in the county of Essex, Commonwealth of Massachusetts, have in- ,loqvented an Improvement in Stitch-Impression Machineaof which the following description, in conneci. tion with the accompanying drawings, is a specificaf tion,,like letters on the drawings representing like This-invention aims to provide an improved machineiorf producing what are known as stitch impres- I sions upon the sole extensions of boots and shoes.

upon the frame base. The free end of the arm i connected with the lower end of a pull rod 40 that controls the separation of the cooperating members,

relationship for performing work upon theshoe. When however, the treadle is depressed, it first acts to dis-' engage the clutch and cut off the power, and by further and continued movement, separate the working devices to free the work.

To enable the operator to leave the machine at rest at any time without attendance and with no one to hold position. This constitutes one form of means for controlling the clutch independently of the treadle.

The machine head A, as here shown, comprises two carries the work support, for introduction and removal shoe sole with-a pressure that may be radially adjusted by means of the wheel 0 Should the sole not be in position, this spring actuated movement is arrested by the stop screw 4;

pivot 3, has bearings for one section of the wheel shaft d, fitted at its rear end with a gear mhee1i1in mesh with m refers sufiicient player and driven by,a P1111011 F011 and prefembly i'ormingg looseness of fit between the gears d, d v being maintained to permit the necessary swing of frame 2 for the introduction of the work between the table and the impression wheel. At its front endsaid shaft section d is connected by a'universal joint d with a second or front I section of the frame shaft, d", which latter is journaled in a bearing box d carried in a yoke d depending from the front end of the swing frainepart 2. This box d is 1 supported from below upon-a spring d seated in the bottdm of the yoke, which spring presses the said box upward against the adjustable stop screw d tapped through the swinging frame 2. The inner end of thebearing box d that is in front of theuniversal fioint is square, or other-wise properly shaped to enter between and-beguided by the armsofa fork-d onand form-i-ng-a pm of the fixed Frame 1, so that the =alinement of said bearing box and the shalt section carried with it is always maintained relative to the fixed frame 1., and

the work support carried thereby. The tront end of theshaitsectiond" is fitted to receive the stem e of the irusto-conical impression wheel e show-n best -in Figs.

' front end with a bevel gear f in mesh with a larger wheel 3, journaled loosely in an arm of the .frameand provided at its upper end with the work supporting table f". This table is rotated positively by and tram the shaft a, which latter in turn is driven from the wheel shaft d by the intermeshing wheels a and a, in order that the surface speed of'the work table, ata point under and opposite the impression wheel e, may correspend exactly with that of the said wheel. By-causing the work table thus to travel in the same direction as the impression wheel and at the same speed, the operator is better able to feed and guide the work, particulaz ly when rounding pointed toes of shoes. It will be yident that-the rotation of the work table tends natufally to swing thet'oe end of a shoeunder; and to be impressed by the wheel e, while at the same time tending to feed the shoe inward toward the impression wheel instead of outward and away from it. To receive this inward thrust and also to prevent damage to the shoe upper by contact with the face of the impression wheel,

' I have provided a guard 11. (Figs, 7 and 8-) which P8!- tially encircles the outer end of said wheel and is properly smoothed and-shaped to permitthe shoe upper to be pressed against it without damage. Preferably this guard inclosesor covers approximately 1} the front face of the impression wheel. 1

To lift the wheel away from the work supporting table for the introduction and removal of the work, the

drop rod 0 (Fig. l is fitted with a roller stud c, which overlies the short end of a lever 0 i'ulcrumed upon the frame at 0 and connected at itsinner end with the rod 5 fro'm the work table to permit of introduction of the said edge. Upon its release, the tresdli rises and first drops the swing-frameimtil the impression wheel rests I 2 co -ere upon the sole edge, and then moves in the clutch and starts the machine. Simultaneous rotation of the im-. pression wheel and -work supporting table causesthe' sole edge to be fed between them and at the same time to be impressed at its upper face by the corrugations or ridges of the impression wheel.

I have found that the action of the impression wheel 1 in feeding or assisting in feeding the work, tends to distort what would otherwise be the impressions made by its ridges or corrugations and to eliminate this errm' and enable the said wheel while feeding to produce at the same time a perfectly symmetrical impression in the work, I have formed the corrugations or ridges thereof so that the sides of the same are notexactly symmetrical or even. j

Reforming to Fig. 5, for instanca lthe loading tacos 5-of thenidges (thedirectionof feed being as indicated by the arrow) are more abnupt' than the following faces 6, they being tangent, for instance, to a circle, 7.,while the following faces 6 are tangent to alarger circle 8, so that the elongation of the stock produced by engagemerit of the loading or pushing faces of the ridges, re-

salts in producing an inclined taco upon the work that I is perieotlysyr nmetrical when compared with the op posits faces produced by the following tacos of the wheel ridges. I believe to be entirely new in ,mschines-of this type.

Thezimpression wheel'ofmachins as heretofore made, have usuahly been provided with ridges or corrugations that taper in depth irom the la'sger-towardthe smaller end of the wheel, much as the teeth of a beveled gear taper irom the base toward the apex of the pitch cone, and since it is the larger end of am impl es sion wheel that travels next the upper, the'smaller end traveling along the outer edge of the sole, it :is evident that the impressions at-and near the outer edge of the sole, which ought for the best efiect to be the more pronounced, are instead produced by the smaller end of the wheel and are more shallow than-at their oppo-.

site or inner ends where more or less concealed in the crease of the shoe and where if-at all they should be The surface speed of the wheel at the large end there-- of, is, of course, higher than that at the small end; while the stock is fed at a speed whichis a mean between the two; consequently the stock impressed by the deeper corrugations at the large end'of the wheel, must be compacted more or less relative to the iced,

and thereby made to appear deeper whileat the smaller end of the wheel, next the outer and exposed edge-of the sole, where the stock is led at a higher speed the sm'iacespeedct the wheelthereat, the :stock is stretched and flattened more or less between the adjacent and already too shallow corrugations thorcat.

This stretching of the stock tends to reduce thedepth. of impression, and, the wheels cutas heretofore,

presenting shallower depressions next the innsrzdiameter, where the tecndency to stretch and flatten is great-e l" est the very formation of the wheellras been calculated not only to permit but to emphasize the tendency tov produce shallow indentations at the outer sole edge where they should be deepest. By cutting the impression wheel in accordance with my invention, however, with the depressions deepened at the smaller diameter of .the wheel as compared with what may be termed, ionwant of a loetter term, the true conical depth thereof, the flattening of the corrugation, by stretching, is

counteracted, and, the required depth of impression is assured. The result is an impression effect to the eye that is symmetrical and uniform when viewed by the eye. Thus, the shapes of the ridges or corrugations upon the-wheel correct the error that results from the feed of'the stock, and also the error that heretofore has resulted from the necessary use of a frusto-conical wheel thesmaller diameter of which travels along that edge of the sole where the-best and most pronounced impression effect should be produced.

Referring to Fig. 2: the angle of presentation of the impression wheel 'to the work supporting table, may. I be adjusted to fit any angle of presentation of the welt in ordinary practice, by means of the stop scr'ew d and spring 1? which raise or lower the said wheel to vary its alinement relative to its shaft section d, and thereby changes its angle of presentation to the work support- I ing table and the work thereon. In any adjusted position of said wheel it is held by the spring 6- r Fig. 1 in contact with the work whatever the position of the latter. I By holding the impression wheel in place by means wholly at the rear thereof, as by the clamping screw acting upon the wheel stem e, the front face of the wheel may be retained smooth and unbr0ken,that is, free from the presence of any fastening means, such as might bruise or mar an upper contacting therewith.
